l Be it known that I, ETHAN Piqua, in the county of Miami and State of Ohio, have invented certain new and useful Improvements in lVlultiplyingCameras, of which the following is a specification.

My invention relates to new and useful improvements in cameras, and more particularly to cameras of the multiplying type.

The object of the invention vis to provide means adapting a roll film to a multiplying camera whereby two or more rows of exposures on one roll of film may be obtained.

preceding a more particular description of the invention general reference is made to the accompanying drawings, of which Figure l is a perspective view of a camera having my invention applied. The rean shutters are open in this view to disclose the interior, and facilitate illustration. Fig. 2 is a section of the line 2-2 of Fig. 1. Fig. 3 is a section on the line 3 3 of Figs. 2 and 4. Fig. Il is a section on the line 4-4 of Figs. 2 and 3. Fig. 5 is a detail sectional view of the focusing gear on the line 5 5 of Fig. 2. Fig. 6 is a rear elevation of the camera. Fig. 7 is a detail sectional view of one of the film spools and its winding key and Fig. 8 is an end view of one of the film spools.

In a more particular description of my invention similar reference characters denote the same parts as they appear in the several views of the drawings.L

In carrying out my invention, I so construct the camera that two or more rows of exposures may be obtained on one roll of film successively. This object may be,

accomplished either by shifting the light chamber relatively to the film or theiilm relatively to the light chamber, whereby, in either case, any number of exposures of one size, or a number of exposures of different sizes may be had on one film- Means for accomplishing both operations are illustrated in the accompanying drawings and will be described more in detail as' the description proceeds.

The lens opening --1- is in a sliding lens board -23- at the front of the camera. -28- designates the right and left sides of the camera. To the inner side of the lens slide -23- and in the rear of the lens ll HUNTZINGER," a citizen of the United States, resldlng at4 arts-are broken away to which the removable open frame-27'` 4 is mounted. The opening 2- insaid frame -27- varies in accordance with the size of the picture. The lens slide 23- is moved as indicated in Figs. 1 and 3, in horizontal guides -18-4 on the top and bottom 22- of the camera. The light housing M12 projects into the film chamber -42- which is inclosed by side and bottom and top walls -49--49` and the rear door Brwhich are parts of the camera structure. `ber thus formed are partition walls 2l-4 and -29 which form a chamber in the /camera in which the film chamber housing is located and into which light does not enter when the lens board 2S- is shifted. When the said lens board is shifted the movement thereof is not sufficient in either direction to expose the space on the inside of the walls l-21 and 29-. The film roll Q5- as is commonly understood has one end secured in a slot -31- in a winding spool which is inclosed at the ends by flanges -fS-,v the spool having an opening -50- in one end and a cross slot 47 in the other end, see Fig. 7 The film spools are supported at one end upon spring -7- attached to the inner side of one of the light chamber walls -49-, and at the other end saidA spools are supported on the winding shafts -30- which have on their inner ends blades 4S- which enter the cross slots 475- in the ends of the spools. The winding shafts project through oblong slots in the outer inside wall -21- and through oblong slots -43- in the sidewall 28 of the camera. The exposed ends of the winding shafts 30'- are fitted with finger pieces -36 by which the shafts are turned to unwind and rewind the film -25-. elongated slots are so formed in order to not interfere with the lnecessary movements of the film box in the operation of focusing. Over the said slots on the outside of the camera, similar shaped slotted plates 35- are placed for finish. The film is guided On each side of the film cham-v The said piece -37- by which to turn said screw to has side adjustment on these tracks to shift the position of the film laterally to expose the film cross-wise. This lateraladjustment is accomplished by means of a screw 11 which engages the lower carriage 2G- and extends through the intermediate wall 21 and the outer wall -28- of the camera, and is there provided with a finger adjust the film cross-wise of the camera The carriages 26 also have guide slots which receive guide strips or tracks to guide t and bottom of the, film chamber e same in the focusing movements. These movements are accomplished b means of a rack -8- secured to a side wa l of the film chamber 42, and a pinion -9 in mesh with said rack. The pinion 9 is splined to the focusing shaft -24- on the top which has bearing in the intermediate wall -2land outer wall -28- of the camera. The shaft 24fhas a finger piece -38- on the outside of the camera by which said shaft is turned in focusing. On the outside of one of the side walls of the film chamber has fixed to it in proximity to the rack -8-- a plate 'or keeper 46+- with an oblong opening therein through which the Vfocusing shaft 2.4- extends. The slot is provide the film is marked through the lower slot in" the slide -44-, and after exposure, the film is wound until the mark is seen through the lupper slot in the slide 44-, and the back o the film is marked through the lower slot for each successive exposure. 4The outer door -14- of the camera is hinged below at -45-'and the same has an opening -4- therein through which film markings through the slides `44 may be performed. While I have described my invention with some detail in order that the statute ma be properly observed and conformed to, do not wis to be understood as meaning that the details are vital in every case to the successful carrying out of my invention, for on the contrary changes may be made in such details without departing from the underlying rinciples of the invention, which compre end means whereby rows of exposures onone roll film may be obtained.

Having described my invention, I claim In a camera having lens and light chambers, a laterally movable slide upon which the said lens and light chambers are supported, a box adapted to su port a r'oll film, said box being a part of the camera structure and into which the light chamber is projected, said roll film supporting box being adjustable laterally relative to the light chamber, and means for imparting focusing movements to said roll film supporting box whereby two 4or more transverse rolls of exposures may be obtained on a roll film.

In testimony whereof I affix my signature.

ETHAN HUNTZINGER.
